Biology

marishachu [46]4 years ago

Answer:

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.  

Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.

svp [43]

Answer:

the answer is Newton's third and Second law

Explanation:

Newton's second law tells us that the force that is generated on a body is proportional to the acceleration it acquires.

F= M*A

at lower mass greater acceleration

Newton's third law explains that for each force that acts on a body, it performs a force of equal intensity and direction but in the opposite direction to the body than gender.

Challenge: A chemical equation is balanced when each side of the equation includes the same number of each type of atom.
nirvana33 [79]
If the reactants are the same the equations are balance but if the reactants are not the same you have to make them balance, however if the reactants are not balance  in order to balance the equation you need to use coefficient to balance the reactants and products of particular chemical reaction.
yet for Photosynthesis the equation 
CO_2 + H_2O => C_6H_12O_6 + H_2O + O_2
Find the ugliest Compound in equation and do not balance first the repetitive Element.
A)So the ugliest one is C_6H_12O_6 and the C is not repetitive and have six atoms so there fore we multiply 6 as coefficient with carbon dioxide.
6CO₂+ H₂O → C₆H₁₂O₆+H₂O+O₂ but oxygen will get 12 atoms because is to all Carbon dioxide.
B) Then we have carbon balanced then we are going to balance Hydrogen, yet on product side it have 14 but on the reactant side it have 2 but Oxygen on product side is 9 there but on reactant side we have 1 so there fore we have to multiply water on reactant side by 12 and on product side multiply water with six and in addition multiply oxygen with 6 which land you at:
6CO₂+ 12H₂O → C₆H₁₂O₆+6H₂O+6O₂.
so we will have 24 hydrogen and 24 oxygen on both sides. 
Hope that helps you.

baherus [9]

Answer:

The correct answer is A.) Sister chromatids are pulled apart.

Explanation:

This is because during Anaphase II in Meiosis, the sister chromatids are pulled apart.

Chromosome pairs line up during Prophase I. <em>Not B.</em> When the chromosome pairs pair up this is also Metaphase I. <em>Not C.</em> When chromosome pairs are pulled apart, Anaphase I is occurring.

Hope this helps,

This is should be told by the nurse in a nice and emphatic manner, especially in this case wherein patients diagnosed with HIV are particularly emotionally sensitive. While this is true, the nurse should not advise the patient to stop taking his or her supplements; especially being diagnosed with HIV, his or her immune system is very frail and needs more than the usual nutrients compared to the normal population. </span></span>
